4 Claims.

This invention relates to looms and more particularly to devices for holding and carrying away the drop wires of the warp stop motion with the harness when dismounting a warp from the loom 5 for the purpose of twisting in a new warp.

In the usual loom practice, the loom fixer, when dismounting the warp from the loom for the purpose of twisting in a new warp, removes therewith the harness, the drop wires of the stop motion being removed from the warp threads, which wires remain at the loom until the warp is replaced. After the new warp is twisted in, the warp and harness are replaced in the loom and an operative mounts the drop wires of the warp stop motion on the warp threads.

It is an object of this invention to provide a device for holding and carrying away the drop wires of the warp stop motion with the harness in order that a new warp may be twisted and drawn through the harness Without the necessity of remounting the drop wires of the warp stop motion at the loom.

Another object of this invention is to provide a frame for holding a bank of drop Wires of the warp stop motion which will be simple, durable and inexpensive in construction and efficient in operation.

Other objects of this invention, together with certain details of construction and combinations of parts, will be described in the specification and pointed out in the appended claims.

The drop wire holder according to the invention comprises a frame which is preferably of exactly the same size and shape as the ordinary heddle frames used in making up the loom harness, a separate frame being preferably employed for each bank of drop wires. The frame is provided with horizontally extending rods, slats or other members which are threaded through and support the wires but allow free movement of said wires from side to side. If necessary, another rod is mounted in the frame to prevent the warp threads from dropping out of the wires.

A form of drop wire frame according to the invention will now be described by way of example, reference being had to the accompanying drawing which shows a preferred form of the device, with the frame partly broken away, supporting a bank of drop wires in proximity to the heddle frame.

Referring more particularly to the drawing the reference numeral 1 indicates an ordinary heddle frame, a number of which are used to make up the loom harness. The heddle frame is provided with cross rods 2 on which are mount.- ed heddles 3 through the eyes 4 of which is threaded the warp 5.

The device for supporting the drop wires comprises a frame generally indicated by reference to numeral 6 having vertical bars 7 and cross-bars 8 and 9. This frame is preferably of the same size and shape as the heddle frame, the arrangement being such that the drop wire frames may be very conveniently tied to the loom harness and 5. supported on the twisting frame while the new warp is being twisted in. The lower cross-bar 9 is detachably secured to the vertical bars 7 for a purpose hereinafter set forth. The vertical bars are provided with slots 11 in which are slidably mounted rods 12, 13 and 14 of any suitable material.

For removing the drop wires 15 together with the loom harness from the loom, the cross-bar 9 is first removed from the frame 6 in order that the frame may be set over the warp and is then reset and fastened in its position. The rods 12 and 13 are now inserted through slots 11, passed through the contact openings 16 in the drop wires and into slots in the vertical bar which is broken 0 away. The latter slots are of course similar to slots 11 which are shown. For the purpose of preventing the warp threads from dropping out of the wires, rod 14 is inserted through the forked portion 1'7 of the drop wires. In the construction 5 above outlined, the rods 12 and 13 not only support the drop wires 15 but allow free movement thereof from side to side.

It will be understood that one drop wire frame of the type illustrated is used for each bank of drop wires in the warp stop motion, but if desired one frame having suflicient thickness and a plurality of sets of slots for each bank of drop wires may be employed. The cross-bars 8 and 9 of the device shown on the drawing are made slightly thicker than the width of the drop wires thereby preventing the drop wires from touching each other and chafing and/ or cutting the warp threads when several banks of drop wires are tied together.

It will thus be seen that I have produced a drop wire frame which can be produced at a comparatively low cost and which, because of its light and simple construction, can be readily handled. 05

It is to be understood that the foregoing detailed description is given merely by way of illustration and that many variations may be made therein without departing from the spirit of my invention.

Having described my invention, what I desire to secure by Letters Patent is:

1. In a loom having a harness comprising a plurality of heddle frames, and a warp stop motion comprising a plurality of banks of drop wire spaced from said heddle frames, means for holding said drop wires for removal from the loom, said means including a frame and means supported by said frame for carrying the drop wires, the said drop wire frame being substantially of the same size and shape as the heddle frames whereby the simultaneous removal of the harness and the drop wires from the loom is facilitated.

2. In a loom having a harness comprising a plurality of heddle frames and having a plurality of banks of drop wires of a warp stop motion spaced from said heddle frames, means for supporting each bank of drop wires for removal from the loom, said means comprising a frame and rods supported by said frame for carrying said drop wires, the said drop wire frame being substantially of the same size and shape as the heddle frames whereby the simultaneous removal of the harness and drop wires is facilitated.

3. In a loom having a harness comprising a plurality of heddle frames and having a plurality of banks of drop wires of a warp stop motion spaced from said heddle frames, means for supporting each bank of drop wires for removal from the loom, said means comprising a frame having openings therein and rods for carrying said drop wires supported in said openings, the said drop wire frame being substantially of the same size and shape as the heddle frames whereby the simultaneous removal of the harness and drop Wires is facilitated.

4. In a loom the combination with a harness comprising a plurality of heddle frames and a plurality of stop motion devices spaced from said heddle frames and associated with warp threads, of means for supporting said devices for removal from the loom, said means comprising a frame and plurality of rods for carrying said devices, one of said rods being adapted to retain the warp threads in association with said warp threads upon their removal from the looms, the said drop wire frame being substantially of the same size and shape as the heddle frames whereby the simultaneous removal of the harness and drop wires is facilitated.
